SECTIONAL RADIATOR,

Patented July 18, 1922.

Application filed August 28, 1920. Serial No. 406,589.

To all to 710m it may concern Be it known that I, ROY OSHKOSH, a citizenof the United States, residing at Manitowoc in the county of Manitowocand State of VVisconsimhave invented new and useful Improvements inSectional Radiators, of which the following is a specification.

This invention relates to radiators for automobiles and has for itsobject the provision of a radiator which is formed in separate sections,any one of which may be removed in the event that it springs a leak andthe resultant spaces normally provided for communication between theupper and lower tanks being closable by plates so that in the event ofan accident injuring the radiator a quick repair may be made.

An important object is the provision of a device of this character inwhich the construction is such thatthe sections, which are preferablyof. the honey comb type, are made in interchangeable units so that whena section leaks from damage or other reason. it may be replaced by asimilar section without necessitating the unsightly patching orsoldering necessary in the ordinary radiator, the sections being held inplace between the upper and lower tanks merely by screws.

An additional object is the provision of a radiator of this characterwhich will be simple and inexpensive in manufacture, highly eflicient inuse, durable in service, and a general improvement in the art.

With the above and other objects and advantages in View, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings inwhich- Figure 1 is a front elevation of a radiator constructed inaccordance with my invention, parts thereof being broken away and insection,

Figure 2 is a vertical sectional view,

Figure 3 is a cross sectional view on the line 33 of Figure 1.

Figure 4 is a detail view of one of the sections detached,

Figure 5 is a plan View of the end thereof,

Figure 6 is a perspective view of one of the emergency closure plates,and

Figure 7 is a front elevation of a modified form.

Referring more particularly to the drawings, I have shown my radiator ascompristion.

and 22 in the upper and lower tanks.

ing upper and lower tanks 10 and 11, respectively, and as shown inFigure 1,the upper tank has an angular under surface, as clearlyindicated. These tanks are of ordinary'construction and are providedwith water inlet and outlet pipes 12 and 13,'respectively. The tanks 10and 11 are of ordinary construction, that is they are formed ofsheet'metal, preferably brass, of suitable gage and soldered orotherwise secured together at their seams. The upper tank'lO isprovided. with the usual filling neck 14 provided with a closure cap 15.The lower tank 11 has associated therewith right angularly extendingbracketsloa'dapted for attachment upon the frame of an automobilewhereby to secure the radiator in posi- It is also apparent that thelower tank 11 may be provided with-the usual drain cook 17.

As is the ordinary practice, my radiator structure is enclosed withinthe usual shell 18 which is ordinarily formed of sheet iron suitablyenameled and which is for the purpose of presenting a pleasingappearance and this shell is secured to the upper and lower tanks bymeans of suitable screws 19. Disposed between the upper and lower tanksare separate sections 20, each of which of the honey comb type and thesesections establish communication between the upper and lower tanksthrough openings 21 and 22 in the lower and upper faces thereof, arespectively.-

Each section 20 comprises side walls 23 and upper and lower end walls 24and 25, respectively, and the honey comb structure is soldered to thesewalls with the openings at the upper and lower ends of the honey combstructure registering with holes 24* and 25 in the upper and lower walls24 and 25 which register with the openings 21 It is of course necessarythat the upper and lower end walls 2a and 25 of the sections be care- Ifully fitted or ground so that they will fit snugly against the upperand lower tanks so as to prevent leakage. The various sections 20 aresecured in position between the upper and lower tanks by means of capscrews 26 which pass through the upper and lower end walls 24 and 25 andwhich are" threaded into lapped holes in the lower and upper walls ofthe upper and lower tongues, respectively.

As shown in Figure l, the upper tank 10 has its under surface or lowerside angular and the screw receiving holes therein must therefore alsobe angular and in this instance I provide the upper end walls of thesections with triangular shaped reinforcements 2?, as clearly shown inFigure I, so that the cap screws will extend longitudinally with respectto the sections 20.

In Figure 7 I have shown the upper tank 28 as having a horizontal lowersurface 29. In other respects this form is identically the same as thefirst described form, the only difference being that in the secondmentioned form there is no necessity for the triangular reinforcements27 as the cap screws pass directly through the upper ends of thesections and into the lower wall of the upper tank at right anglesthereto.

In the use of the radiator it will be seen that if a section is damagedit may be readily removed and replaced by another similar section merelyby removing the eight cap screws which hold each section in position. Inactual practice it may be found that the meeting :taces oi the sectionsand tanks should be shellacked prior to securing a section in positionso as to form a water-tight joint.

In case of emergency, as for instance in case of accident which willproduce a serious leak in one of the sections, the section may beremoved entirely after which a pair of plates 30 may be seemed upon theunderside of the upper tank and upon the upper side of the lower tank tocover the openings 21 and 22. This plate is of course 01? the same sizeand shape as the end of a section and must be accurately fitted so as toform a liquid tight joint when bolted in place by the cap screws.

From the foregoing description and a study of the drawings it will thusbe apparent that I have provided a simply constructed and inexpensiveradiator structure for automobiles which is sectional and in which anysection may be removed and replaced by another without disassembling theentire radiator and without any necessity whatever for soldering. It isalso apparent that in case of emergency a leaking section may be removedand a pair of closure plates secured in position to take the place ofthe missing section until the proper replacement can be effected.

lVhile I have shown and described the preferred embodiment of myinvention, it is 01 course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit oi the invention or the scope of thesubjoined claim.

Having thus described my invention. I claim:

An automobile radiator comprising upper and lower tanks, the upper tankbeing provided in its bottom with a plurality of openings and a seriesof threaded holes, the lower tank being provided in its top with aplurality of openings and a series of threaded holes, a plurality 01?sections disposed between said tanks and having their upper and lowerends flat to conform to the bottom and top of the upper and lower tanksrespectively, said sections being disposed in contacting relations toone another, cap screws carried by the upper and lower ends of thesections and threa-dedly engaged within said threaded holes in thebottom of the upper tank and top of the lower tank, and said fiat endsbeing provided with openings registering with the openings in the tanks,the sections being removable.

In testimony whereof I a'liix my signature.

ROY OSHKOSH.
